Can’t get in through that one without a code. Can get in, but can’t get out of this one without an electronic fob. Can’t do anything without a master key, but noone knows where it’s gone, at this one! Need to have your photo taken by a robot and get a bar code to get through these ones. Admin will let you out of this one...if she happens to see you ( her office window is at an angle from the door, meaning she can’t see you unless she gets up.) . I forever seem to be getting locked in, out or having to run back round to the main entrance! Is it just me?
